If a given code is needed at the beginning and end of a program (or part), such as a M08 (air blast on) and a M09 (air blast off), that code can be entered in the Before Code and After Code fields. This eliminates the need for inserting it manually in a text editor and the possibility of forgetting to add the code
Note: You must enter the codes correctly, for example M08 not M8. Please refer to the your Post Processor Application Notes for specific codes for your machine.
